Cetearyl Alcohol: A Multifunctional Fatty Alcohol in Cosmetics
Cetearyl Alcohol is a blend of cetyl alcohol and stearyl alcohol, both derived from natural sources such as coconut oil or palm oil, or produced synthetically. Despite the word “alcohol,” it is not a drying alcohol—instead, it’s a waxy, fatty alcohol that conditions, thickens, and stabilizes cosmetic products.
